Trevali Mining Corporation ("Trevali" or the "Company") (TSX: TV) (BVL: TV) (OTCQX: TREVF) ( Frankfurt : 4TI) announces that it has published its 2020 Sustainability Report, covering new performance targets and disclosures.

"Our third annual Sustainability Report marks another substantial milestone in bringing us closer to fulfilling our purpose in becoming the world's most sustainable mining company" said Ricus Grimbeek, President and CEO. The unprecedented events of 2020 remind us how critical sustainability planning is for the people and communities that host us, not only during a crisis but in the years ahead. It also highlights the role our industry plays in protecting the planet. Sustainability is core to our business and is an integral part of our decision-making processes, driving us to contribute to a greener and safer global economy. Over the years, the excellent planning of our teams allowed us to achieve our sustainability goals in 2020, deliver on production guidance, reduce debt and bring a mine out of care and maintenance during the pandemic. We continue to adopt innovative practices, use new technologies, and achieve net-positive outcomes for society and the natural environment while delivering value for our shareholders despite the challenges of 2020."

Trevali believes that metals critical for the world's transition to a low carbon society must be mined responsibly. Zinc, lead, and silver are used in low-carbon technologies, which enable the transition to electric vehicles and renewable energy. The Company mines these metals in a socially and environmentally responsible way, to mitigate risks and protect the value of the business for our stakeholders over the long-term.
